Hello Chiobe,
the double radiator setup at the bottom is supported in stacking mode and if the PSU is mounted in the other stacked case. There is no alternative space for the PSU intended.
The same applies to the drive cages. Up to 3 drives can be installed at the ODD slots, however.
Also, a radiator can only be mounted at the side without PSU/drive bays. This means the maximum amount of radiators at the same time (non-stacked) is 6 (1 front, 1 rear, 1 side, 2 top, 1 bottom).
If you give us a rundown of what you want to do, we can check if that is possible - or you can read a review (a couple are already published). Since the cases are exclusively distributed through some key clients with online shops, it is not possible to have a look at the chassis at the store next door.
